With GCC 9.2.1 net/nfs.c leads to multiple errors of type
address-of-packed-member.
net/nfs.c: In function ‘rpc_req’:
net/nfs.c:199:18: error: taking address of packed member of
‘struct rpc_t’ may result in an unaligned pointer value
[-Werror=address-of-packed-member]
199 | p = (uint32_t *)&(rpc_pkt.u.call.data);
| ^~~~~~~~~~~~~~~~~~~~~~
net/nfs.c: In function ‘nfs_readlink_reply’:
net/nfs.c:631:46: error: taking address of packed member of
‘struct rpc_t’ may result in an unaligned pointer value
[-Werror=address-of-packed-member]
631 | nfs3_get_attributes_offset(rpc_pkt.u.reply.data);

struct rpc_t is only used as local variable. It is naturally packed. So
there is no need for the attribute packed.
